ACE'IYLENE-GAS GENERATOR.

Specification of Letters Patent.

Application filed April 8, 1915. Serial No. 20,046.

To all whom it may concern:

Be it known that. I, GEORGE K. CooswnLL, a citizen of the United States, residing at Darlow, in the county of Reno and State of Kansas, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

This invention relates to an improved acetylene gas generator and the principal object of the invention is to provide a generator of such construction as to permit gas to be generated in a selected generating tank while the second tank is being discharged for cleaning and to also provide an im proved purifying mechanism for the gas prior to the gas entering the service pipe.

Another object of the invention is to provide an improved type of generating tank and to also provide within the generating tank an improved type of carbid holding receptacle. V

Another object of the invention is to pro.- vide. a device of this character which eflectuallyexcludes the entrance of air into the distributing pipes 7 when it is being recharged.

Another object of the invention is to minimize the waste of gas when the device is being recharged.

Another object of the invention is to provide an'acetylene gas generator of the class described which will be very compact .and thus take up a small amount of room and at the same time be very strong, the various parts being securely held in place and thus preventing it from having any movement ivhich would cause the various joints to work oose.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view of thegenerator showing one of the tanks in elevation and the second tank in verticalsection.

Fig. 2 is a view of the generator showing one of the tanks and the purifying chambers in top plan and the second generating tank in section along the line 22 of Fig. 1.

The generating tanks 10 and 11 are positioned within the base frame 12 and are com nected by the conduit pipes 13 so that water may pass from one tank into the other thus permitting both tanks to be filled by pouring water into one of the tanks through the spout 1 1 shown upon tank 10. If desired each of these tanks may be provided with a spout 1 1 thus permitting the tanks to be rapidly filled by pouring water through both of the spouts simultaneously. a

Each of the tanks is provided with a bell 15 which is slidably mounted within the respective tank and has its lower end portion reinforced by the band 16 which band is formed of channel iron as clearly shown in Fig. 1. The conical top or head 17 of each bell 15 is provided with a collar or flange 18 at its junction with the body portion of the bell, this flange engaging the upper edge of the tank and reinforcing band 19 which latter is positioned'about the upper edge thereof above the spout 1 1 and cooperates with the flange 18 so as to limit the downward movement of the bell within the tank and suspend the same therein. Brackets 20 are positioned within the tank and engage thelower end of the bell to support the same and prevent. the entire weight of the bell from being placed'upon the flange or collar 18. Danger of the collar being bent or broken from overstrain is therefore eliminated.

The head 17 of the bell 15 is formed with a central opening which is closed by a cover 21 which is provided with a flange which rests upon the upper edge portion or neck 22 of the head 17 except when it is normally raised from said neck. The cover 21 comprises a cylindrical portion or flange 23 which is closed at its upper end and open at its lower end, as clearly illustrated in Fig. 1. A double-walled water jacket 24:, having a closed lower end and an open upper end, has its outer wall secured to the neck 22 by a fluid-tight joint, while its inner wall is spaced apart from the outer wall sufliciently to allow free movement of the cylindrical portion 23 of the cover 21, and also provides a space at. each side of the ele ment 23 for containing a water seal for preventing" the passage of gas from the bell 28 provided with hooks 29'at their free ends to engage the perforated carbid receptacle 30 and suspend the same in the positionshown in Fig. '1 so that the carbid willbe submerged in the water with which the gen.- erating tank is filled. It should be noted that the Walls of the bell 15 are positioned in spaced relation to the walls of the generat-' ingtanks and therefore a water seal will be provided preventing the carbids from leaking out ofthe bell when the generator is in operation.

The purifying tanks 31 and 32' are placed within the frame 12 between the generating tanks 10 and 11 and upon opposite sides of the frame and are connected with the outlet pipes 33'a-nd 34 leading from a point within the bell above the water line to a point adjacent thebottom of the tank and out through the same and communicating with the lower end portions of its purifying tank. Refen ring to Fig. 1, it will be noted that the outlet'pipe33 has its upper end opening into an annular chamber between the water jacketf24 and the inner wall er the bell 15, and that said water jacket extends below the normal level of water in the tank 15, While the pipe 83 opens a considerable distance above the Water level. Therefore, when the bell 21 is removed for recharging the ap- 'parat-us, the annular space into which the pipe 33 opensvremains hermetically sealed,

thereby preventing escape of gas fromthe bell 1'5, and at the same time preventing the entrance of air into the bell 15 .orinto the pipe 38. The purifying tanks may be filled with any suitable filtering material such as mineral wool or any material which will :cleansethe' gasand remove moisture from the same so that when the gas passes out through the service pipes 35 and 36 it will. be clean and dry and thusburnwell. These pipes can-be directed tothe gas mains supplying the-house andcan be provided With separate; control valves so that .gas may :be

fed from one tank at a time while the other is being recharged "or cleaned or they may be led to a suitable storage tank where the gas can be stored until needed-for use. A small pet cock 317 is placed in the pipe 33 so that; the'pipe'can be .drained of any water or. other fluid which'may collect the same and'a drainrpipe 38 leads from the 1pipe84; toa rpoint adjacent the tank3l where it-is also provided with a pet cock .39 permitting the fluid collecting in the fpipe 38 "to. ,be

drained put.

' ovement. said water. j acketlhavinga@losed ott, f open top .anda icent'ral When this device is in use carbids may be placed Within one of the receptacles 30 after the tanks have been filled with Water and after the receptacle 30 has been placed between the resilient arms 28 of the U-shaped supporting bracket 27 the cover is put in T0 place as shown in Fig. 1 with the carbid receptacle submerged? The carbid will then be dissolved by the water until sufficient gas has been generated to raise the bell and move the'receptacle 30 out of the water-. Th'e'b'ell will provide sufiicient pressure-to 7 force; the gas through the outlet pipe and into the purifying tank through Which it will pass and thenthrough the service pipes to the house. As the gas is used the hell will gradually de'scendun'til the carbid .receptacle is again immersed and more gas will be generated until the bell is again raised a s'utlicientdistance to raise the carbid receptacle out of the water. After all of the carbid in the receptacle has been used second ta can be charg and thegeegfi t d in the second tankean be camera-. to the building through its service pipe while the first tank is being recharged. I is of course better to charge-the second before the gas in the first tank is completely used so that'there will be no time when the upply of a wi x u te 9 me if desired for any reason to have an unusr u y-..laree, quant o er Supp e a time b t ar-1k? 95 b sim ltaneously. r.- era and ite b the n m l qua ti y f gas provided." When desired toaclean the tanks the cover is removed and the-carbid receptacles can then ,be' emptied vwithout it being necessary tojremove the bell. Water collecting in-the outlet pipes 33 and 3.4. be drawn off through the pet cocks7 and 39 and When necessary the water can he removed from the generating tanks 19 and .11.
